Background

   Water conditions around the Apostle Islands National Lakeshore (AINL), Lake Superior, vary dramatically due to sheltering effects, rapidly changing winds from fast-moving storms, and reflection from steep cliffs (Fig. 1). Wave conditions are generally most sheltered near the mainland (where boaters launch) and increase in intensity toward the open waters of Lake Superior, which may cause boaters to underestimate wave conditions. Recent boating accidents are an unpleasant reminder of the potential dangers [CBS News, 9/3/2018, Father, three children killed, mother survives; NYPost, 5/2/2020, Person missing after boat capsizes off Long Island].

   With the goal of improving boater awareness and safety, we have developed Water Information for a Safe Coast (WISC)-Watch to provide real-time wave and water temperature conditions around the AINL. WISC-Watch is a network of SOFAR Spotter buoys (see Fig. 2 below) that have been strategically placed at many of the most popular boating destinations. Furthermore, ongoing outreach is being conducted by UW-Sea Grant to promote the use of real-time data and gather feedback about boating habits in the area. Outreach is a critical component we intend to use to optimize the system and achieve our project goal.

   This project is a joint effort between a multitude of partners and collaborators. Funding has been provided by the Wisconsin Coastal Management Program, UW-Sea Grant, and Professor Chin Wu of UW-Madison. Deployment and maintenance of the buoys is conducted by Josh Anderson of UW-Madison, Karl Carlson and Lance Twombly of the AINL, and Tara Krall and Eric Peterson of the Iron County Forestry Dept. Please reach out if your organization is interested in collaborating!

   WISC-Watch is constantly evolving as scientific and public data are gathered and analyzed. Below (Fig. 3) is a map of the original layout of WISC-Watch buoys in 2021, which differs slightly from the 2022 configuration. Adjustments to buoy locations were made for many reasons, but one important contribution was boater feedback. So, please keep offering your suggestions!
